<h1>Summary</h1>
<p>Time of creation: Thu May 11 20:48:00 CST 2023</p><h2>Introduction</h2><p>This summary is automatically generated. To maximize the level of details in the summary, complete the following tasks before running this function: <ul><li>clustering and labeling by using the <b>All in One</b> button</li><li>run the burst detection function from the <b>Burstness</b> tab in the Control Panel</li><li>compute the betweenness centrality from the Nodes menu</li><li>save the current visualization as a PNG image in the project folder</li></ul>The summary highlights major clusters first, including citing articles and cited references. The importance of nodes will be summarized in terms of citation-based metrics such as citation counts and citation bursts, network-based metrics such as degree centrality and betweenness centrality. Sigma is a combination of both types, i.e., burst and betweenness centrality.</p><p>There are other features that are not included in the current summary, for example, structural variation analysis, analysis of uncertainties, concept trees, and dual-map overlays.</p><h2>MAJOR CLUSTERS</h2>
